To all whom it may concewt:

Be it known that we, EDWARD B. LOO-MKS and GALEN Q. Looms, citizens of the United States, residing at Memphis, in the county of Shelby and State of Tennessee, have invented certain new and useful Improvements in Ventilators; and i do declare the following invention consists of certain novel features of construc tion, combination end arrangement of pelts, as will be more fully described alnd particularly pointed out inthe appended c suns. r

In the accompanying drawings, Figure l is a front elevation, Fig. 2 is a'vertical sec tional view on the line 2.-2 of Fig. 1, and Fig. 3 is a similar section on the line 33 of Fig. 1.

Referring more especially to the drawings, 1 represents the frame of the window, and 2 and 3 the lower and u per sashes, which are 'slidably mounted wit in: the frame, as is p .hination with a pair of members, of means usual.

7. These reduced ends are overlspped and,

the outer one of the two forming a port of the member 5 is covered by arnetallic plate 8,

which is slotted at 9, to register with similar slots 10, formed in the reduced end? so as to accommodate the adjusting bolts, .1 1-, which pass through apertures formed, in the reduced end of the member 4. The reduced end of the member 4 is provided also witha longitudinal groove 12, which is engnged hy arib 13, carried u on the reduced end of the member 5 an arrsned in between the two adjusting bolts 11. as: rib end groove ere adapted to keep the members in elinement.

Epechhostion of Letters Patent.

. Application filed Eloy 31, 18%. lierial Ho. 84,171.

The ventilator comprises a'psir of meme racemes-est. e,

I The entire device is beveled upon its top and hottornsides as at i5,fto conform to the shape of the sill and the lower her-of the lower sash, and each member is provided with en elon 'ated epertiire 16, for the pun poseot venti ation.

In 0 oration the device is inserted between the si and the bar of the lower sash, as

'shown in. Fig. 3 and the members adjusted toward or away irons each other so as to place the ends of each member 4 and 5 between the parting strip and the head of the lower sash. This will allow considerable fresh air to enter between the upper and lower sashes, and also permits considerable air to pass through the apertures 16.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the iuven tion will be readily understood without requiring a more extended explanation.

Various changes in the iorm, pi-oportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention as defined in the appended claims. p

.Having thus described our invention, what we claim and desire to secure by Lettors Patent 'is:-

In a device of the class described, the oomr for holding said members in alinement with each other, a pair of bolts carried by one of said members and ads ted to enter adjustin'g slots in the other 0? said. members, nuts carried by 'said holts whereby the members may he held in sdjusted position, and bev- -eled edges to fit the sill'and sash, said members each having 9. diagonally disposed elongated ventilating slot.

In testimony whereof we have hereunto set our hands in presence of two subscribing witnesses.
